I have a white rock hen as it says above that can't stand up. This just happened yesterday and I found her crawling around. She's alert,eating, and drinking. I have her inside my house because my other hens were picking on her. If this helps when she was younger (like at 15-17 weeks old) she had difficulty walking it seemed because she walked like it took effort to walk. Also I picked her up to make sure her legs still work and they both do but she can't stand.
